JOHN H. UTTER, OF NEW? YORK, N. Y.

PRINTING-PRESS.

Speccation of Letters Patent No. 18,477, dated October 20, 1857.

T0 all whom it may concern:

Be it known that I, JOHN H. UTTER, of the city and State of New York,have invented certain new and useful Improvements in Printing-Presses;and I do hereby declare the following to be a true and eX- actIdescription of the same, reference being had to the accompanyingdrawings, in which- Figure 1 is a front view; Fig. 2, a plan; Fig. 3, aside elevation, and Fig. 4, a vertical section with the parts inposition for receiving the sheet; the same letters referring to likeparts in all the figures.

The nature of my invention consists in so combining a series of leverswith a swinging platen, that one motion of the hand lever performs allthe operations of print-ing, with the exception of feeding and flyingthe sheets, namely: inking the form, turning down the platen and givingthe impression; together with a new method of actuating the inkingrollers and the frisket.

The press is constructed as follows: The bed Z), is supported in ahorizontal position upon a frame-work, a, of suitable form anddimensions, and is capable ofbeing adjusted for the purpose of'varyingthe impression by means of four setscrews, c, upon which it rests. At asuitable point, cl, in the frame is hinged a platen, e, in such a mannerthat it is capable of being turned from a horizontal position to anangle suitable for receiving the sheet, as shown in Fig. 4; this platenserves the purpose of the platen and tympan in common hand presses, andhas the blanket attached to its surface.

Under the center of the bed, and across the. frame, is placed a shaft,f, upon each end of which is a lever, g. These levers are connected to apiece, It, which acts as a lever and has one of its ends attached to theplaten, or they may be each attached to separate levers which aresimilarly attached to the platen in a line which, at the moment ofgiving the impression, will be directly `over and parallel with theshaft, f. There are also, upon shaft f, a hand lever, i, by which it isoperated, and a weight, .76, for the purpose of balancing the platen.The arrangement of these levers is such, that when the hand lever, z',is carried from the position shown in Fig. 4 to that shown in Fig. 8,the platen, e, is turned over upon the form which is placed upon bed, b,and as the levers g and L, come into the same plane they exert apowerful progressive leverage at the moment it is wanted for giving theimpression. When the hand lever, 27, is returned to its former position,the platen is also carried back, ready to receive another sheet.

AThe inking apparatus is peculiar, and is constructed as follows: Thereis a cylinder, Z, hung in the frame, in contact with which is avibrating roller, m, which receives its motion from a crank. In aframework, n, are hung two inking rollers, 0, 0, by means of centers orother equivalent device. These rollers lie upon the cylinders, Z, whenthe platen is in the position shown in Fig. 4, and receive their supplyof ink therefrom. The framework, fn., is attached to the platen, c, bymeans of connections, p, in such a manner that when said platen isbrought into the horizontal position, the framework with its rollers ispushed before it, traveling upon bearers, r, on each end of the bed,inking the form, assuming the position shown in Fig. 3 while theimpression is being given, and returning to the cylinder as the platenassumes its former position.

Between the legs of the platen is hung a shaft, s, to which is attacheda frisket, t, which is closed upon the platen by a spiral spring notshown in the drawing, and is opened by means of a cam, w, attached tothe frame, acting upon a toe, o, on shaft s, or it may be operated byany equivalent device giving the same motion. Said frisket is for thepurpose of holding the sheet to the platen during its movement, andremoving it from the type after the impression is given. l

The manner of operation is as follows: The operator turns roller m, bymeans of its crank, thus distributing the ink, and then lays a sheet ofpaper upon the platen, c. He now grasps the lever, t', and brings itdown to nearly a horizontal position. As the platen is brought over, thefrisket. t, meets it before it reaches the perpendicular position, andthey together turn over upon the type,-rollers 0, o, meantime inking thefemmand the impression is given by the levers g and h. Lever, z', is noWraised to its former position carrying back the platen, inking rollers,and risket, when toe, o, striking cam w, opens the risket and releasesthe sheet Which is removed and the same process repeated.

I do not Wish to be conned to a horizontal bed, as I also intend makingit perpendicular, in which case I may attach power to lever z', or g.Neither do I Wish to be confined to one platen, as I can also use tWo,operating alternately7 one attached to each side of the bed. I alsocontemplate arranging it so that the ink will be distributed by themotion of the press; but intend it to be chiefly used as abovedescribed.

I do not claim, broadly, actuating the platen by means of the impressionlevers, as that has been previously done, neither do I claim giving animpression by means of the leverage herein described, but

What I do claim as my invention and desire to secure by Letters Patent,is

1. The combination of the platen, e, levers g, L, z', and shaft f, Whenarranged as set forth.

9. I claim connecting the inking rollers to the swinging platen, bymeans of rods p,

or theirequivalent, in such a manner that 30 JOHN H. UTTER. WitnessesWM. D. WINES, GEO. B. UTTER, JOHN M. MosHER.
